一个ajax和rails交互的例子
首先，这里用了一个，query信息解析的包，如下https://github.com/rapportive-oss/jquery-parsequery
主要做如下：
$.parseQuery({query: "id[]=1&id[]=2", array_keys: /^ids$/, decode: function (input, context) { input = this.default_decode(input); if (context === null) { return input.replace(/\[\]$/, 's') } else if (context === "ids") { input = parseInt(input); if (isNaN(input)) { throw URIError("id was not a number"); } } return input; }}) == {'ids':}
例子，正式触发
// If direct link to property query is used send to Railstry {var hash = location.hash.substr(1, location.hash.length);if (location.pathname == '/properties' && hash.length > 0) { $.parseQuery.separator = ','; var data = $.parseQuery(hash); $.ajax({ url : '/properties', type : 'GET', data : data, dataType : 'script' });}} catch(err) { }
